HINGE. t

SPECIFICATION forming part of Letters Patent No. 540,646, dated June 11,1895. Application filed November 1, 18951. $erialN0. 527,606.(llomodeli) To all whom it may concern:

Be it known that I, WILLIAM B. DEMING, a

' citizenof the United States, residing at Bentonville, in the county ofBenton and State of Arkansas, have invented certain new and usefulImprovements in Hinges; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in strap hinges and has for itsobject the construction of a right angled re-inforcing plate of theclass shown in Letters Patent No. 518,309, issued to me on the 17th dayof April, 1894, but with an improvement in the construction whereby theplate after passing through the slotted leaf will follow the curvatureof the knuckle a suitable distance before the bend is made, to bring thebent section of the plate in line with the verticalcenter of the hingepin, in order to obviate the necessity of mortising the door jamb orpost.

I accomplish the objects of the invention by the mechanism illustratedin the accompanying drawings, in which Figure l is a view in perspectiveof a straphinge securedto a door-jamb and provided with areinforcing-plate made in accordance with this invention. Fig. 2 is adetail in horizontal section of a portion of the post and door, andshowing the hinge and my reinforcingplate in top or plan view. Fig. 3 isa detail in side elevation of a portion of a hinge in which thereinforcing-plate in the part overlying the strap of the hinge isbroadened to cover the full width of the strap and in which the plate isriveted to the hinge. Fig. 4:. is a detail in front view of a portion ofa hinge, showing the enlarged slot through which the reinforcing-plateis passed; and Fig. 5 is a top or edge view of the reinforcing-platedetached from the hinge. 7

Similar letters refer to like parts throughout the several views of thedrawings.

A represents the door jamb or gate post.

B and B are the two leaves of a strap hinge of common construction savethat the space B (shown in Fig. 4:), is deepened to an amount equal tothe thickness of a reinforcing plate which will be projectedtherethrough.

C, is the reinforcing plate above referred to and in the constructionshown in Fig. 1, consists of a short bar of strap iron bent at a pointabout midway between its ends so as to form two plates which will standapproximately at right angles to each other. In the construction shownin my former patent, above referred to, the meeting ends of the twoplates form a sharp corner which causes the plate which is thrustthrough the slot in the hinge to stand tangentially with relation to theknuckle of the hinge.

The longitudinal axis of the knuckle of a hinge when the hinge isproperly applied, should be directly opposite the dividing line betweenthe door and post, but where the plate as above described, is tangentialto the knuckle it is necessary either to let the plate into the post bymortising, or else leave a wide space or crack between the post and thedoor.

In my present construction, instead of making a sharp corner at thejunction of the two plates I make the inside curve 0 (Fig.5) conformingto the curvature of the knuckle and so proportioned as to align theplatewith the axis of the pintle of the hinge instead of presenting itin a position tangential to the knuckle. By this construction, when thehinge is placed as it should be, with the vertical axis of theknuckleopposite the meeting line of the jamb or post, and the door, the plate Cwill be exactly opposite the meeting line. A neat job will thus besecured without mortising. This reinforcing plate may be sold as anattachment detached from the hinge or it may be permanently riveted, orsecured in any other mechanical manner, to the hinge. The plate may alsobe formed as an integral portion of the leaf of the hinge in which casethe right angled attaching plate will have an indented curved portionconmeeting it with the leaf. The part overlapping the hinge may be wideenough to cover the entire leaf or it may be of less dimensions.

Having thus fully described my invention, what I claim as new,-and wishto secure by Letters Patent of the United States, is-

1.- The combination, with. the pintle and leaves of a strap hinge, oneof which leaves is cut away opposite to the knuckle or eye of the otherleaf, so as to leave a slot when such knuckle or eye is placed inposition, of a reinforcing piece bent to form two plates at right anglesto each other of which one overlies the said cut away leaf and the otheris adapted to pass through said slot, said two plates be ing connectedby a section of the piece integral with the two plates but formed aroundthe corner which otherwise would have been made by the junction of thetwo plates, and thereby affording an unobstructed space for theadjustment of the plates around the knuckle of the hinge whereby theknuckle will occupy the said corner space and whereby the plate passedthrough the slot will be aligned with the axis of the knuckle,substantially in the manner as described and for the purposes specified.
